Delta Airlines BMAR Test
What Is the Delta Airlines BMAR Test and How Can You Pass It?
The BMAR (Basic Mechanical Aptitude and Reasoning) test is designed to measure your understanding of mechanical concepts, spatial awareness, and problem-solving skills. Whether you’re aiming to become an Aircraft Maintenance Technician or a Ground Support Mechanic, knowing what to expect on this test can give you a clear edge over the competition.
What Is the Delta Airlines BMAR Test?
The BMAR (Basic Mechanical Aptitude and Reasoning) test is a pre-employment screening tool designed to evaluate your understanding of mechanical principles, reasoning ability, and spatial awareness. It is often used for technical and maintenance roles to ensure candidates possess the foundational knowledge needed to work on complex systems like aircraft engines, hydraulics, and ground equipment.
Key Areas Covered in the BMAR Test
The Delta BMAR test typically includes the following sections:
| Section | Description |
|---|---|
| Mechanical Principles | Questions on levers, pulleys, gears, springs, gravity, and basic physics |
| Spatial Reasoning | Tests your ability to visualize objects in 3D or rotate them mentally |
| Troubleshooting/Problem Solving | Practical reasoning based on mechanical scenarios |
| Tools and Workplace Safety | Familiarity with common tools and safe work practices |
Sample BMAR Questions
Mechanical Principles
Question: If one pulley is twice the size of another, how will this affect the speed of the belt system?
Answer: The smaller pulley will rotate faster to compensate for the larger one’s slower rotation.Spatial Reasoning
Question: Which figure shows the correct 3D object after folding the net?
Answer: You’ll need to mentally fold the shapes and choose the correct 3D match.Tools and Safety
Question: What tool is most appropriate to loosen a rusted bolt?
Answer: A wrench with lubricant, or a torque wrench, depending on the torque needed.
